There's a new ShapelyDeprecationWarning in graph.py that will cause an error in Shapely 2.0. Not sure why it appears and therefore didn't find a way to fix it.
vresutils/graph.py:529: ShapelyDeprecationWarning:
__len__ for multi-part geometries is deprecated and will be removed in Shapely 2.0. Check the length of the `geoms` property instead to get the number of parts of a multi-part geometry.

I think the warning appears somewhere here: https://github.com/FRESNA/vresutils/blob/master/vresutils/graph.py#L528-L530
